臥式靜電除塵器是眾多除塵器當中的一種，臥式靜電除塵器是以靜電凈化法來收捕廢氣中的粉塵的設備，其主要是讓含塵氣體進人氣刺叭時，含塵氣體受到氣流分布板以及折流板的調整后，使氣流能較均勻地進人電場。

工作原理(li)

靜(jing)電(dian)(dian)除塵(chen)(chen)(chen)(chen)器的(de)工作(zuo)(zuo)原理是利用高(gao)(gao)壓電(dian)(dian)場使煙(yan)氣發生電(dian)(dian)離，氣流(liu)中的(de)粉塵(chen)(chen)(chen)(chen)荷(he)電(dian)(dian)在電(dian)(dian)場作(zuo)(zuo)用下與(yu)氣流(liu)分離。負極(ji)(ji)由不(bu)同斷面形(xing)狀的(de)金(jin)屬(shu)導線(xian)制成，叫放(fang)電(dian)(dian)電(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不(bu)同幾(ji)何(he)形(xing)狀的(de)金(jin)屬(shu)板制成，叫集塵(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)。靜(jing)電(dian)(dian)除塵(chen)(chen)(chen)(chen)器的(de)性(xing)(xing)能受(shou)粉塵(chen)(chen)(chen)(chen)性(xing)(xing)質(zhi)、設備構造(zao)和煙(yan)氣流(liu)速等三個因素的(de)影(ying)(ying)響。粉塵(chen)(chen)(chen)(chen)的(de)比(bi)(bi)電(dian)(dian)阻是評價導電(dian)(dian)性(xing)(xing)的(de)指(zhi)標，它對除塵(chen)(chen)(chen)(chen)效率有直接(jie)的(de)影(ying)(ying)響。比(bi)(bi)電(dian)(dian)阻過(guo)低(di)，塵(chen)(chen)(chen)(chen)粒(li)難以保(bao)持在集塵(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)上，致使其重返氣流(liu)。比(bi)(bi)電(dian)(dian)阻過(guo)高(gao)(gao)，到達集塵(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)的(de)塵(chen)(chen)(chen)(chen)粒(li)電(dian)(dian)荷(he)不(bu)易放(fang)出，在塵(chen)(chen)(chen)(chen)層之間形(xing)成電(dian)(dian)壓梯度(du)會(hui)產生局部擊穿和放(fang)電(dian)(dian)現象(xiang)。這些(xie)情(qing)況都(dou)會(hui)造(zao)成除塵(chen)(chen)(chen)(chen)效率下降。

電除塵(chen)器的(de)基(ji)本原理是(shi)利用電力捕集煙氣(qi)中的(de)粉塵(chen)，主要包(bao)括以下四個相互(hu)有關的(de)物理過程: (1) 氣(qi)體(ti)的(de)電離。(2) 粉塵(chen)的(de)荷電。(3) 荷電粉塵(chen)向電極移動。(4) 荷電粉塵(chen)的(de)捕集。
